=== Bootloader
[NOTE]
This section refers to the **default** NEORV32 bootloader.
.Pre-Built Bootloader Image
[IMPORTANT]
This section refers to the **default** NEORV32 bootloader. A pre-compiled memory image for the processor-internal
<<_bootloader_rom_bootrom>> is available in the project's +rtl+ folder: `rtl/core/neorv32_bootloader_image.vhd`.
This image is automatically inserted into the boot ROM when synthesizing the processor with the bootloader being
enabled. **Note that the default bootloader image was compiled for a minimal `rv32i` + priv. ISA!**
The NEORV32 bootloader (`sw/bootloader/bootloader.c`) provides an optional built-in firmware that
allows to upload new application executables at _any time_ without the need to re-synthesize the FPGA's bitstream.
